FIELD OF THE INVENTION

The present invention relates to a novel class of compounds which are activators of AMP-activated protein kinase (AMPK) (AMPK-activators), compositions comprising said compounds, methods of synthesis and uses for such compounds in treating various diseases mediated by AMPK, such as type 1 (Type I) diabetes, type 2 (Type II) diabetes, metabolic syndrome, atherosclerosis, dyslipidaemia, mitochondrial disorders, sarcopenia, obesity, hypertension, cerebral ischemia, cognitive defect, neurodegenerative diseases (including but not limited to Alzheimer's disease, Parkinson's disease, Huntington's disease), neurological and mitochondrial disorders (including but not limited to schizophrenia, Friedrich's Ataxia, amyotrophic lateral sclerosis, multiple sclerosis), neuroinflammation, inflammatory pain, neuropathic pain, epilepsy, cardiac ischemia, virus infection (HIV, cytomegalovirus and hepatitis C) or cancer.

BACKGROUND OF THE INVENTION

AMPK has been established as a sensor and regulator of cellular energy homeostasis (Hardie, D. G. and Hawley, S. A. AMP-activated protein kinase: the energy charge hypothesis revisited. Bioessays 23: 1112 (2001), Kemp, B. E. et. al. AMP-activated protein kinase, super metabolic regulator. Biochem. Soc. Transactions 31:162 (2003)). Allosteric activation of this kinase due to rising AMP levels occurs in states of cellular energy depletion. The resulting serine/threonine phosphorylation of target enzymes leads to an adaptation of cellular metabolism to the low energy state. The net effect of AMPK activation induced changes is inhibition of ATP consuming processes and activation of ATP generating pathways, and therefore regeneration of ATP stores. Examples of AMPK substrates include acetyl-CoA-carboxylase (ACC) and HMG-CoA-reductase (Carling, D. et. al. A common bicyclic protein kinase cascade inactivates the regulatory enzymes of fatty acid and cholesterol biosynthesis. FEBS Letters 223:217 (1987)). Phosphorylation and therefore inhibition of ACC leads to a decrease in fatty acid synthesis (ATP-consuming) and at the same time to an increase in fatty acid oxidation (ATP-generating). Phosphorylation and resulting inhibition of HMG-CoA reductase leads to a decrease in cholesterol synthesis. Other substrates of AMPK include hormone sensitive lipase (Garton, A. J. et. al. Phosphorylation of bovine hormone-sensitive lipase by the AMP-activated protein kinase. A possible antilipolytic mechanism. Eur. J. Biochem. 179:249 (1989)), glycerol-3-phosphate acyltransferase (Muoio, D. M. et. al. AMP-activated kinase reciprocally regulates triacylglycerol synthesis and fatty acid oxidation in liver and muscle: evidence that sn-glycerol-3-phosphate acyltransferase is a novel target. Biochem. J. 338:783 (1999)), malonyl-CoA decarboxylase (Saha, A. K. et. al. Activation of malonyl-CoA decarboxylase in rat skeletal muscle by contraction and the AMP-activated protein kinase activator 5-aminoimidazole-4-carboxamide-1-.beta.-D-ribofuranoside. J. Biol. Chem. 275:24279 (2000)), some of which are potential drug targets for components of metabolic syndrome. Additional processes that are believed to be regulated through AMPK activation, but for which the exact AMPK substrates have not been identified, include stimulation of glucose transport in skeletal muscle and expressional regulation of key genes in fatty acid and glucose metabolism in liver (Hardie, D. G. and Hawley, S. A. AMP-activated protein kinase: the energy charge hypothesis revisited. Bioessays 23: 1112 (2001), Kemp, B. E. et. al. AMP-activated protein kinase, super metabolic regulator. Biochem. Soc. Transactions 31:162 (2003), Musi, N. and Goodyear, L. J. Targeting the AMP-activated protein kinase for the treatment of Type 2 diabetes. Current Drug Targets-Immune, Endocrine and Metabolic Disorders 2:119 (2002)). For example, decreased expression of glucose-6-phosphatase (Lochhead, P. A. et. al. 5-aminoimidazole-4-carboxamide riboside mimics the effects of insulin on the expression of the 2 key gluconeogenic genes PEPCK and glucose-6-phosphatase. Diabetes 49:896 (2000)), a key enzyme in hepatic glucose production, and SREBP-1c (Zhou, G. et. al. Role of AMP-activated protein kinase in mechanism of metformin action. The J. of Clin. Invest. 108: 1167 (2001)), a key lipogenic transcription factor, has been found following AMPK stimulation.

More recently an involvement of AMPK in the regulation of not only cellular but also whole body energy metabolism has become apparent. It was shown that the adipocyte-derived hormone leptin leads to a stimulation of AMPK and therefore to an increase in fatty acid oxidation in skeletal muscle (Minokoshi, Y. et. al. Leptin stimulates fatty-acid oxidation by activating AMP-activated protein kinase. Nature 415: 339 (2002)). Adiponectin, another adipocyte derived hormone leading to improved carbohydrate and lipid metabolism, has been demonstrated to stimulate AMPK in liver and skeletal muscle (Yamauchi, T. et. al. Adiponectin stimulates glucose utilization and fatty acid oxidation by activating AMP-activated protein kinase. Nature Medicine 8: 1288 (2002), Tomas, E. et. al. Enhanced muscle fat oxidation and glucose transport by ACRP30 globular domain: Acetyl-CoA carboxylase inhibition and AMP-activated protein kinase activation. PNAS 99: 16309 (2002)). The activation of AMPK in these circumstances seems to be independent of increasing cellular AMP levels but rather due to phosphorylation by one or more yet to be identified upstream kinases.

Based on the knowledge of the above-mentioned consequences of AMPK activation, certain beneficial effects could be expected from in vivo activation of AMPK. In liver, decreased expression of gluconeogenic enzymes could reduce hepatic glucose output and improve overall glucose homeostasis, and both direct inhibition and/or reduced expression of key enzymes in lipid metabolism could lead to decreased fatty acid and cholesterol synthesis and increased fatty acid oxidation. Stimulation of AMPK in skeletal muscle could increase glucose uptake and fatty acid oxidation with resulting improvement of glucose homeostasis and, due to a reduction in intra-myocyte triglyceride accumulation, to improved insulin action. Finally, the increase in energy expenditure could lead to a decrease in body weight. The combination of these effects in metabolic syndrome could be expected to reduce the risk for acquiring cardiovascular diseases.

Several studies in rodents support this hypothesis (Bergeron, R. et. al. Effect of 5-aminoimidazole-4-carboxamide-1(beta)-D-ribofuranoside infusion on in vivo glucose metabolism in lean and obese Zucker rats. Diabetes 50:1076 (2001), Song, S. M. et. al. 5-Aminoimidazole-4-darboxamide ribonucleoside treatment improves glucose homeostasis in insulin-resistant diabeted (ob/ob) mice. Diabetologia 45:56 (2002), Halseth, A. E. et. al. Acute and chronic treatment of ob/ob and db/db mice with AICAR decreases blood glucose concentrations. Biochem. and Biophys. Res. Comm. 294:798 (2002), Buhl, E. S. et. al. Long-term AICAR administration reduces metabolic disturbances and lowers blood pressure in rats displaying feature of the insulin resistance syndrome. Diabetes 51: 2199 (2002)). Until recently most in vivo studies have relied on the AMPK activator AICAR, a cell permeable precursor of ZMP. ZMP acts as an intracellular AMP mimic, and, when accumulated to high enough levels, is able to stimulate AMPK activity (Corton, J. M. et. al. 5-Aminoimidazole-4-carboxamide ribonucleoside, a specific method for activating AMP-activated protein kinase in intact cells? Eur. J. Biochem. 229: 558 (1995)). However, ZMP also acts as an AMP mimic in the regulation of other enzymes, and is therefore not a specific AMPK activator (Musi, N. and Goodyear, L. J. Targeting the AMP-activated protein kinase for the treatment of Type 2 diabetes. Current Drug Targets-Immune, Endocrine and Metabolic Disorders 2:119 (2002)). Several in vivo studies have demonstrated beneficial effects of both acute and chronic AICAR administration in rodent models of obesity and Type 2 diabetes (Bergeron, R. et. al. Effect of 5-aminoimidazole-4-carboxamide-1(beta)-D-ribofuranoside infusion on in vivo glucose metabolism in lean and obese Zucker rats. Diabetes 50:1076 (2001), Song, S. M. et. al. 5-Aminoimidazole-4-darboxamide ribonucleoside treatment improves glucose homeostasis in insulin-resistant diabetic (ob/ob) mice. Diabetologia 45:56 (2002), Halseth, A. E. et. al. Acute and chronic treatment of ob/ob and db/db mice with AICAR decreases blood glucose concentrations. Biochem. and Biophys. Res. Comm. 294:798 (2002), Buhl, E. S. et. al. Long-term AICAR administration reduces metabolic disturbances and lowers blood pressure in rats displaying feature of the insulin resistance syndrome. Diabetes 51: 2199 (2002)). For example, 7 week AICAR administration in the obese Zucker (fa/fa) rat leads to a reduction in plasma triglycerides and free fatty acids, an increase in HDL cholesterol, and a normalization of glucose metabolism as assessed by an oral glucose tolerance test (Minokoshi, Y. et. al. Leptin stimulates fatty-acid oxidation by activating AMP-activated protein kinase. Nature 415: 339 (2002)). In both ob/ob and db/db mice, 8 day AICAR administration reduces blood glucose by 35% (Halseth, A. E. et. al. Acute and chronic treatment of ob/ob and db/db mice with AICAR decreases blood glucose concentrations. Biochem. and Biophys. Res. Comm. 294:798 (2002)). In addition to AICAR, more recently it was found that the diabetes drug metformin can activate AMPK in vivo at high concentrations (Zhou, G. et. al. Role of AMP-activated protein kinase in mechanism of metformin action. The J. of Clin. Invest. 108: 1167 (2001), Musi, N. et. al. Metformin increases AMP-activated protein kinase activity in skeletal muscle of subjects with Type 2 diabetes. Diabetes 51: 2074 (2002)), although it has to be determined to what extent its antidiabetic action relies on this activation. As with leptin and adiponectin, the stimulatory effect of metformin is indirect via a mild inhibition of mitochondrial respiratory chain complex 1 (Leverve X. M. et al. Mitochondrial metabolism and type-2 diabetes: a specific target of metformin. Diabetes Metab. 29: 6588 (2003)). In addition to pharmacologic intervention, several transgenic mouse models have been developed in the last years and initial results are becoming available. Expression of dominant negative AMPK in skeletal muscle of transgenic mice has demonstrated that the AICAR effect on stimulation of glucose transport is dependent on AMPK activation (Mu, J. et. al. A role for AMP-activated protein kinase in contraction and hypoxia-regulated glucose transport in skeletal muscle. Molecular Cell 7: 1085 (2001)), and therefore likely not caused by non-specific ZMP effects. Similar studies in other tissues will help to further define the consequences of AMPK activation. It is believed that pharmacologic activation of AMPK may have benefits in relation to metabolic syndrome with improved glucose and lipid metabolism and a reduction in body weight. To qualify a patient as having metabolic syndrome, three out of the five following criteria must be met: elevated blood pressure above 130/85 mmHg, fasting blood glucose above 110 mg/dl, abdominal obesity above 40″ (men) or 35″ (women) waist circumference, and blood lipid changes as defined by an increase in triglycerides above 150 mg/dl or decreased HDL cholesterol below 40 mg/dl (men) or 50 mg/dl (women). Therefore, the combined effects that may be achieved through activation of AMPK in a patient who qualifies as having metabolic syndrome would raise the interest of this target.

Lowering of blood pressure has been reported to be a consequence of AMPK activation (Buhl, E. S. et. al. Long-term AICAR administration reduces metabolic disturbances and lowers blood pressure in rats displaying feature of the insulin resistance syndrome. Diabetes 51: 2199 (2002)), therefore activation of AMPK might have beneficial effects in hypertension. Through combination of some or all of the above-mentioned effects stimulation of AMPK may to reduce the incidence of cardiovascular diseases (e.g. MI, stroke). Increased fatty acid synthesis is a characteristic of many tumor cells, therefore decreased synthesis of fatty acids through activation of AMPK could be useful as a cancer therapy (Huang X. et al. Important role of the LKB1-AMPK pathway in suppressing tumorigenesis in PTEN-deficient mice. Biochem J. 412: 211 (2008). AMPK can also be considered as a metabolic tumor suppressor and AMPK activators could be helpful in general cancer therapy (Luo Z. Et al. AMPK as a metabolic tumor suppressor: control of metabolism and cell growth. Future Oncol. 6: 457 (2010)). Pharmacological activation of the LKB1/AMPK/mTOR axis using known AMPK activators such as metformin, AICAR or A-769662 induce in most studies a dramatic suppression of cancer cell growth, demonstrating that the reinforcement of the tumor suppressive functions of LKB1/AMPK is a valuable therapeutic strategy for both solid tumors (such as breast or prostate cancer) and hematological cancers (such as acute myeloid leukemia or chronic myelogenous leukemia) (Green A. S. et al. LKB1/AMPK/mTOR signaling pathway in hematological malignancies: From metabolism to cancer cell biology. Cell Cycle 10: 2115 (2011). Micic D. et al. Metformin: Its emerging role in oncology. Hormones 10:5 (2011)). The connection of AMPK with several tumour suppressors suggests that therapeutic manipulation of this pathway using AMPK activators warrants further investigation in patients with cancer such as Peutz-Jeghers syndrome, a dominantly inherited cancer-predisposition syndrome in which, at least 80% of all reported cases are caused by mutations that inactivate the gene encoding LKB1 (chromosome 19p13.3), AMPK upstream kinase (Shackelford D. B.; Shaw R. J. The LKB1-AMPK pathway: metabolism and growth control in tumour suppression. Nature Rev. Cancer 2009, 9: 563 (2009). Carling D. LKB1: a sweet side to Peutz-Jeghers syndrome? TRENDS in Molecular Medicine 12: 144 (2006)).

Stimulation of AMPK has been shown to stimulate production of ketone bodies from astrocytes (Blazquez, C. et. al. The AMP-activated protein kinase is involved in the regulation of ketone body production by astrocytes. J. Neurochem. 73: 1674 (1999)), and might therefore be a strategy to treat ischemic events in the brain. Stimulation of AMPK has been shown to improve cognition and neurodegenerative diseases in a mice model (Dagon Y. et al. Nutritional status, cognition, and survival: a new role for leptin and AMP kinase. J. Biol. Chem. 280:42142 (2005)). Stimulation of AMPK has been shown to stimulate expression of uncoupling protein 3 (UCP3) in skeletal muscle (Zhou, M. et. al. UCP-3 expression in skeletal muscle: effects of exercise, hypoxia, and AMP-activated protein kinase. Am. J. Physiol. Endocrinol. Metab. 279: E622 (2000)) and might therefore be a way to prevent damage from reactive oxygen species. Endothelial NO synthase (eNOS) has been shown to be activated through AMPK mediated phosphorylation (Chen, Z.-P., et. al. AMP-activated protein kinase phosphorylation of endothelial NO synthase. FEBS Letters 443: 285 (1999)), therefore AMPK activation may be used to improve local circulatory systems. AMPK has also been described to directly affect PGC-1alpha activity through phosphorylation and then regulate mitochondria biogenesis (Jager S, et al. AMP-activated protein kinase (AMPK) action in skeletal muscle via direct phosphorylation of PGC-1alpha. Proc Natl Acad Sci 104:12017 (2007)). AMPK activation can be then a way to treat mitochondrial disorders (e.g. sarcopenia and some mitochondrial rare diseases). Recently, several reports describe beneficial effect of AMPK activation on virus infection. While virus infection is found to reduce AMPK activity in infected cells or tissues, AMPK activation is proposed as a anti-viral therapy (Mankouri J. et al., Enhanced hepatitis C virus genome replication and lipid accumulation mediated by inhibition of AMP-activated protein kinase, Proc Natl Acad Sci 107: 11549 (2010)).

The use of AMPK activators may represent a strategy to protect the heart and other solid organs against cardiac ischemia as it has been demonstrated with A-769662 (Kim A. S. et al. A small molecule AMPK activator protects the heart against ischemia-reperfusion injury. J. Mol. Cell. Cardiology 51: 24 (2011)) or metformin (Yin M. et al. Metformin improves cardiac function in a non-diabetic rat model of 2 post-MI heart failure Am J Physiol Heart Circ Physiol 301: H459 (2011)).

Each of the aspects of the invention are independent unless stated otherwise. Nevertheless the skilled person will understand that all the permutations of the aspects herein described are within the scope of the invention. Thus it is to be understood that the present invention covers all combinations of suitable, convenient and exemplified aspects described herein.

As used herein, the term “alkyl” refers to straight or branched hydrocarbon chains containing the specified number of carbon atoms. For example, —C₁₋₄alkyl refers to a straight or branched “alkyl” containing at least 1, and at most 4, carbon atoms.

As used herein, the term “pharmaceutically acceptable”, refers to salts, molecular entities and other ingredients of compositions that are generally physiologically tolerable and do not typically produce untoward reactions when administered to a subject (e.g. human). The term “pharmaceutically acceptable” also means approved by a regulatory agency of the Federal or a state government or listed in the U.S. Pharmacopoeia or other generally recognized pharmacopoeia for use in a subject, and more particularly in humans.

As used herein, the term “subject” refers to an animal, in particular a mammal and more particularly to a human or a domestic animal or an animal serving as a model for a disease (e.g., mouse, monkey, etc.). In one aspect, the subject is a human.

Salts of compounds of formula (I) which are suitable for use in medicine are those wherein the counterion is pharmaceutically acceptable. However, salts having non-pharmaceutically acceptable counterions are within the scope of the present invention, for example, for use as intermediates in the preparation of other compounds of formula (I) and their pharmaceutically acceptable salts.

Suitable pharmaceutically acceptable salts will be apparent to those skilled in the art and include for example base addition salts e.g. ammonium salts, alkali metal salts such as those of sodium and potassium, alkaline earth metal salts such as those of calcium and magnesium and salts with organic bases, including salts of primary, secondary and tertiary amines, such as isopropylamine, diethylamine, ethanolamine, trimethylamine, dicyclohexyl amine and N-methyl-D-glucamine or for example acid addition salts formed from acids which form non-toxic salts e.g. hydrochloride, hydrobromide, hydroiodide, sulphate, bisulphate, nitrate, phosphate, hydrogen phosphate, acetate, maleate, malate, fumarate, lactate, tartrate, citrate, formate, gluconate, succinate, piruvate, oxalate, oxaloacetate, trifluoroacetate, saccharate, benzoate, methansulphonate, ethanesulphonate, benzenesulphonate, p-toluensulphonate, methanesulphonic, ethanesulphonic, p-toluenesulphonic, and isethionate. For a review on suitable salts see Berge et al. J. Pharm. Sci., 1977, 66, 1-19. The invention includes within its scope all possible stoichiometric and non-stoichiometric forms of the salts of the compounds of formula (I).

Those skilled in the art of organic chemistry will appreciate that many organic compounds can form complexes with solvents in which they are reacted or from which they are precipitated or crystallized. These complexes are known as “solvates”.

Solvates of the compounds of formula (I) and solvates of the salts of the compounds of formula (I) are included within the scope of the present invention.

As used herein, the term “solvate” refers to a complex of variable stoichiometry formed by a solute (in this invention, a compound of formula (I) or a salt thereof) and a solvent. Such solvents for the purpose of the invention may not interfere with the biological activity of the solute. Examples of suitable solvents include, but are not limited to, water, methanol, ethanol and acetic acid. Preferably the solvent used is a pharmaceutically acceptable solvent. Most preferably the solvent used is water and the solvate may also be referred to as a hydrate.

Solvates of compounds of formula (I) which are suitable for use in medicine are those wherein the solvent is pharmaceutically acceptable. However, solvates having non-pharmaceutically acceptable solvents are within the scope of the present invention, for example, for use as intermediates in the preparation of other compounds of formula (I) and their pharmaceutically acceptable salts.

In one aspect, the compounds of formula (I) may be in the form of pharmaceutically acceptable salts, solvates or solvates of salts. In a further aspect, the compounds of formula (I) may be in the form of pharmaceutically acceptable salts.

As used herein, the term “compounds of the invention” means the compounds according to formula (I) and pharmaceutically acceptable salts thereof. The term “a compound of the invention” means any one of the compounds of the invention as defined below.

Prodrugs of the compounds of formula (I) are included within the scope of the present invention.

As used herein, the term “prodrug” means a compound which is converted within the body, e.g. by hydrolysis in the blood, into its active form that has medical effects. Pharmaceutically acceptable prodrugs are described in T. Higuchi and V. Stella, Prodrugs as Novel Delivery Systems, Vol. 14 of the A.C.S. Symposium Series, and in Edward B. Roche, ed., Bioreversible Carriers in Drug Design, American Pharmaceutical Association and Pergamon Press, 1987 and in D. Fleishner, S. Ramon and H. Barba “Improved oral drug delivery: solubility limitations overcome by the use of prodrugs”, Advanced Drug Delivery Reviews (1996) 19(2) 115-130. Prodrugs are any covalently bonded carriers that release a compound of structure (I) in vivo when such prodrug is administered to a patient. Prodrugs are generally prepared by modifying functional groups in a way such that the modification is cleaved in vivo yielding the parent compound. Prodrugs may include, for example, compounds of this invention wherein hydroxy or amine groups are bonded to any group that, when administered to a patient, cleaves to form the hydroxy or amine groups. Thus, representative examples of prodrugs include (but are not limited to) phosphonate, carbamate, acetate, formate and benzoate derivatives of hydroxy and amine functional groups of the compounds of formula (I).

Certain compounds of formula (I) may exist in stereoisomeric forms (e.g. they may contain one or more asymmetric carbon atoms). The individual stereoisomers (enantiomers and diastereomers) and mixtures or racemic mixtures thereof are included within the scope of the present invention.

Likewise, it is understood that compounds of formula (I) may exist in tautomeric forms other than that shown in the formula and these are also included within the scope of the present invention. In particular, compounds of formula (I) may exist in the following tautomeric forms.

All possible tautomeric forms of the compounds of formula (I) are contemplated to be within the scope of the present invention.

It will be appreciated that racemic compounds of formula (I) may be optionally resolved into their individual enantiomers. Such resolutions may conveniently be accomplished by standard methods known in the art. For example, a racemic compound of formula (I) may be resolved by chiral preparative HPLC. An individual stereoisomer may also be prepared from a corresponding optically pure intermediate or by resolution, such as H.P.L.C. of the corresponding mixture using a suitable chiral support or by fractional crystallisation of the diastereoisomeric salts formed by reaction of the corresponding mixture with a suitable optically active acid or base, as appropriate.

In one aspect of the invention there is provided a compound of formula (I) selected from the group consisting of:

Pharmaceutical Compositions

While it is possible that, for use in the methods of the invention, a compound of formula (I) or a pharmaceutically acceptable salt thereof may be administered as the bulk substance, it is preferable to present the active ingredient in a pharmaceutical formulation, for example, wherein the agent is in admixture with at least one pharmaceutically acceptable carrier selected with regard to the intended route of administration and standard pharmaceutical practice.

Accordingly, the present invention also includes a pharmaceutical composition comprising a) a compound of formula (I) or a pharmaceutically acceptable salt thereof and b) one or more pharmaceutically acceptable carriers.

The term “pharmaceutically acceptable carrier” refers to a diluent, excipient, and/or vehicle with which an active compound is administered. The pharmaceutical compositions of the invention may contain combinations of more than one carrier. Such pharmaceutical carriers can be sterile liquids, such as water, saline solutions, aqueous dextrose solutions, aqueous glycerol solutions, and oils, including those of petroleum, animal, vegetable or synthetic origin, such as peanut oil, soybean oil, mineral oil, sesame oil and the like. Water or aqueous solution saline solutions and aqueous dextrose and glycerol solutions are preferably employed as carriers, particularly for injectable solutions. Suitable pharmaceutical carriers or diluents are well known in the pharmaceutical art, and are described, for example, in “Remington's Pharmaceutical Sciences” by E. W. Martin, 18th Edition. The choice of pharmaceutical carrier can be selected with regard to the intended route of administration and standard pharmaceutical practice. The pharmaceutical compositions may comprise as, in addition to, the carrier any suitable binder(s), lubricant(s), suspending agent(s) and/or coating agent(s).

The carrier, diluent and/or excipient must be “pharmaceutically acceptable” in the sense of being compatible with the other ingredients of the composition and not deleterious to the recipient thereof.

An “pharmaceutically acceptable excipient” means an excipient that is useful in preparing a pharmaceutical composition that is generally safe, non-toxic and neither biologically nor otherwise undesirable, and includes an excipient that is acceptable for veterinary use as well as human pharmaceutical use.

The present invention further relates to a pharmaceutical composition comprising a) 10 to 2000 mg of a compound of formula (I) or a pharmaceutically acceptable salt thereof, and b) 0.1 to 2 g of one or more pharmaceutically acceptable carriers.

The compounds of the invention may be administered in conventional dosage forms prepared by combining a compound of the invention with standard pharmaceutical carriers or diluents according to conventional procedures well known in the art. These procedures may involve mixing, granulating and compressing or dissolving the ingredients as appropriate to the desired preparation.

The pharmaceutical compositions of the invention may be formulated for administration by any suitable route, and include those in a form adapted for oral, parenteral, transdermal, inhalation, sublingual, topical, implant, nasal, enterally (or other mucosally) administration to mammals including humans. The pharmaceutical compositions may be formulated in conventional manner using one or more pharmaceutically acceptable carriers or excipients. In one aspect, the pharmaceutical composition is formulated for oral administration

The compositions may be in the form of tablets, capsules, powders, granules, lozenges, such as oral or sterile parenteral solutions or suspensions.

Tablets and capsules for oral administration may be in unit dose presentation form, and may contain conventional excipients such as binding agents, for example syrup, acacia, gelatin, sorbitol, tragacanth, or polyvinylpyrrolidone; fillers, for example lactose, sugar, maize-starch, calcium phosphate, sorbitol or glycine; tabletting lubricants, for example magnesium stearate, talc, polyethylene glycol or silica; disintegrants, for example potato starch; or acceptable wetting agents such as sodium lauryl sulphate. The tablets may be coated according to methods well known in normal pharmaceutical practice.

Oral liquid preparations may be in the form of, for example, aqueous or oily suspensions, solutions, emulsions, syrups or elixirs, or may be presented as a dry product for reconstitution with water or other suitable vehicle before use. Such liquid preparations may contain conventional additives, such as suspending agents, for example sorbitol, methyl cellulose, glucose syrup, gelatin, hydroxyethyl cellulose, carboxymethyl cellulose, aluminium stearate gel or hydrogenated edible fats, emulsifying agents, for example lecithin, sorbitan monooleate, or acacia; non-aqueous vehicles (which may include edible oils), for example almond oil, oily esters such as glycerine, propylene glycol, or ethyl alcohol; preservatives, for example methyl or propyl p-hydroxybenzoate or sorbic acid, and, if desired, conventional flavouring or colouring agents.

For parenteral administration, fluid unit dosage forms are prepared utilising the compound and a sterile vehicle, water being preferred. The compound, depending on the vehicle and concentration used, can be either suspended or dissolved in the vehicle. In preparing solutions the compound can be dissolved in water for injection and filter sterilised before filling into a suitable vial or ampoule and sealing.

The compounds of the invention may also, for example, be formulated as suppositories containing conventional suppository bases e.g. cocoa butter or other glyceride for use in human or veterinary medicine or as pessaries e.g., containing conventional pessary bases.

The topical formulations of the present invention may be presented as, for instance, ointments, creams or lotions, eye ointments and eye or ear drops, impregnated dressings and aerosols, and may contain appropriate conventional additives such as preservatives, solvents to assist drug penetration and emollients in ointments and creams.

As indicated, the compound of the present invention can be administered intranasally or by inhalation and is conveniently delivered in the form of a dry powder inhaler or an aerosol spray presentation from a pressurized container, pump, spray or nebulizer with the use of a suitable propellant, e.g., a hydrofluoroalkane such as 1,1,1,2-tetrafluoroethane (HFA 134AT) or 1,1,1,2,3,3,3-heptafluoropropane (HFA 227EA), or a mixture thereof. In the case of a pressurized aerosol, the dosage unit may be determined by providing a valve to deliver a metered amount. The pressurized container, pump, spray or nebulizer may contain a solution or suspension of the active compound, e.g., using a mixture of ethanol and the propellant as the solvent, which may additionally contain a lubricant e.g. sorbitan trioleate.

Capsules and cartridges (made, for example, from gelatin) for use in an inhaler or insufflator may be formulated to contain a powder mix of the compound and a suitable powder base such as lactose or starch.

Advantageously, agents such as a local anaesthetic, preservative and buffering agent can be dissolved in the vehicle. To enhance the stability, the composition can be frozen after filling into the vial and the water removed under vacuum. The dry lyophilised powder is then sealed in the vial and an accompanying vial of water for injection may be supplied to reconstitute the liquid prior to use. Parenteral suspensions are prepared in substantially the same manner except that the compound is suspended in the vehicle instead of being dissolved and sterilisation cannot be accomplished by filtration. The compound can be sterilised by exposure to ethylene oxide before suspending in the sterile vehicle. Advantageously, a surfactant or wetting agent is included in the composition to facilitate uniform distribution of the compound.

The compounds of the invention may be administered for immediate-, delayed-, modified-, sustained-, pulsed- or controlled-release applications.

In one aspect, oral compositions are slow, delayed or positioned release (e.g., enteric especially colonic release) tablets or capsules. This release profile can be achieved, for example, by use of a coating resistant to conditions within the stomach but releasing the contents in the colon or other portion of the GI tract wherein a lesion or inflammation site has been identified. Or a delayed release can be achieved by a coating that is simply slow to disintegrate. Or the two (delayed and positioned release) profiles can be combined in a single formulation by choice of one or more appropriate coatings and other excipients. Such formulations constitute a further feature of the present invention.

Suitable compositions for delayed or positioned release and/or enteric coated oral formulations include tablet formulations film coated with materials that are water resistant, pH sensitive, digested or emulsified by intestinal juices or sloughed off at a slow but regular rate when moistened. Suitable coating materials include, but are not limited to, hydroxypropyl methylcellulose, ethyl cellulose, cellulose acetate phthalate, polyvinyl acetate phthalate, hydroxypropyl methylcellulose phthalate, polymers of metacrylic acid and its esters, and combinations thereof. Plasticizers such as, but not limited to polyethylene glycol, dibutylphthalate, triacetin and castor oil may be used. A pigment may also be used to color the film. Suppositories are be prepared by using carriers like cocoa butter, suppository bases such as Suppocire C, and Suppocire NA50 (supplied by Gattefosse Deutschland GmbH, D-Weil am Rhein, Germany) and other Suppocire type excipients obtained by interesterification of hydrogenated palm oil and palm kernel oil (C₈-C₁₈ triglycerides), esterification of glycerol and specific fatty acids, or polyglycosylated glycerides, and whitepsol (hydrogenated plant oils derivatives with additives). Enemas are formulated by using the appropriate active compound according to the present invention and solvents or excipients for suspensions. Suspensions are produced by using micronized compounds, and appropriate vehicle containing suspension stabilizing agents, thickeners and emulsifiers like carboxymethylcellulose and salts thereof, polyacrylic acid and salts thereof, carboxyvinyl polymers and salts thereof, alginic acid and salts thereof, propylene glycol alginate, chitosan, hydroxypropylcellulose, hydroxypropylmethylcellulose, hydroxyethylcellulose, ethylcellulose, methylcellulose, polyvinyl alcohol, polyvinyl pyrrolidone, N-vinylacetamide polymer, polyvinyl methacrylate, polyethylene glycol, pluronic, gelatin, methyl vinyl ether-maleic anhydride copolymer, soluble starch, pullulan and a copolymer of methyl acrylate and 2-ethylhexyl acrylate lecithin, lecithin derivatives, propylene glycol fatty acid esters, glycerin fatty acid esters, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters, polyethylene glycol fatty acid esters, polyoxyethylene hydrated caster oil, polyoxyethylene alkyl ethers, and pluronic and appropriate buffer system in pH range of 6.5 to 8. The use of preservatives, masking agents is suitable. The average diameter of micronized particles can be between 1 and 20 micrometers, or can be less than 1 micrometer. Compounds can also be incorporated in the formulation by using their water-soluble salt forms.

Alternatively, materials may be incorporated into the matrix of the tablet e.g. hydroxypropyl methylcellulose, ethyl cellulose or polymers of acrylic and metacrylic acid esters. These latter materials may also be applied to tablets by compression coating.

The compositions may contain from 0.1% by weight, preferably from 10-60% by weight, of the active ingredient, depending on the method of administration. Where the compositions comprise dosage units, each unit will preferably contain from 50-500 mg of the active ingredient. The dosage as employed for adult human treatment will preferably range from 100 to 3000 mg per day, for instance 1500 mg per day depending on the route and frequency of administration. Such a dosage corresponds to 1.5 to 50 mg/kg per day. Suitably the dosage is from 5 to 20 mg/kg per day.

Since the compounds of the invention are intended for use in pharmaceutical compositions it will readily be understood that they are each preferably provided in substantially pure form, for example at least 60% pure, more suitably at least 75% pure and preferably at least 85%, especially at least 98% pure (% are on a weight for weight basis). Impure preparations of the compounds may be used for preparing the more pure forms used in the pharmaceutical compositions; these less pure preparations of the compounds should contain at least 1%, more suitably at least 5% and preferably from 10 to 59% of a compound of the invention.

It will be recognised by one of skill in the art that the optimal quantity and spacing of individual dosages of a compound of the invention will be determined by the nature and extent of the condition being treated, the form, route and site of administration, and the particular mammal being treated, and that such optimums can be determined by conventional techniques.

Human recombinant AMPK (Invitrogen #PV4673 & #PV4675) was used in a FRET assay format (Z'Lyte—Invitrogen). Assay conditions were as follow: ATP 100 μM, peptide (Invitrogen #PR8650) 2 μM, 1% final DMSO in Z'Lyte kinase buffer. Reaction was initiated by addition of 0.2-0.8 ng of AMPK and incubated for 1-hour @ 30° C. A further 1-hour incubation @ 30° C. with the development reagent (Invitrogen # PR5194) was performed. FRET signal was then measured and converted to “% peptide phosphorylation” according to Z'Lyte given calculation procedure. Evaluation of compounds was carried out using concentration-response curves. Final data were expressed in “% activation” calculating the ratio of “% peptide phosphorylation” between compound-condition and basal-condition. Alternatively pEC200 (−Log(compound concentration leading to a 2-fold AMPK activity increase)) was produced through fitting of the concentration-response curves. All data were means of at least 2 independent experiments.

The compounds of Examples 1-196 were tested essentially as described above and gave average pEC₅₀ values of greater than or equal to 5.5 or gave average pEC₂₀₀ values of greater than or equal to 5.0.
